Evaluation of different fungicides against stalk rot of Maize caused by Fusarium moniliforme
Maize is the world's leading crop and is widely cultivated as a cereal grain, it is the only food cereal crop that can be grown in diverse seasons, ecologies and uses. Maize yields in Pakistan are very poor due to insect pests and diseases. Among them, the stalk rot of maize caused by Fusarium moniliforme is very important. Keeping in view the huge losses caused by the disease, the present study was conducted to evaluate the efficacy of selected fungicides against the disease development under field conditions and on the plant growth and yield parameters. A total of six fungicides were used such as Scoure, Plyrem, Topguard, Ridomil, Fenatac M, and Cobox with three different concentrations i.e., (50, 100 and 200 ppm). The effect on disease incidence, growth and yield parameters such as plant height, root length, root weight, leaf weight per plant, grain weight, and biological yield (t acre-1) were recorded. The results showed that all applied fungicides significantly affect against stalk rot of maize caused by F. moniliforme. The maximum plant height, root length, root weight, leaf weight per plant, grain weight and biological yield (t acre-1) was noted under Ridomil and Scoure fungicides, followed by Topguard, Cobox, Plyrem and Fenatac M. Whereas, the minimum plant height, root length, root weight, leaf weight per plant, grain weight, and biological yield (t acre-1) was observed under control plants where no fungicides were applied
Description of a new species in the Genus Cosella Newkirk and Keifer (Acari: Eriophyidae) From China
Eriophyoid mites are the most common groups of phytophagous mites found on various plants in Zhejiang Province of China. These mites are usually found on agricultural, horticultural, ornamental, and medicinal plants, including fruit and forest trees. Zhejiang Province is famous for its renowned mountains consist of Yandang, Putuo, Xuedou, Tianmu, Tiantai and Qingliang covered with green forest and wide range of vegetation due to which it is called as a treasure house of plants in China, which provide ecologically suitable living environment for eriophyoids species richness. Because of the diversity of host plants in Zhejiang Province, there is a dire need to investigate the presence of these minute creatures-especially those species that can be harmful to economic crops. Prior to this study genus Cosella Newkirk and Keifer held 43 species worldwide. Further one new leaf vagrant eriophyoid mite species in the genus Cosella was found from Zhejiang Province, China. A survey was carried out to determine the eriophyid mite fauna on natural vegetation of Linan City, Zhejiang Province China. One new species Cosella linanensis sp. nov. is described and illustrated from Rhododendron ovatum (Ericaceae). There was no apparent damage found on host plants where the new species was collected
Comparative performance of top cross and population cross hybrids in white Maize using a common tester
Improved maize populations and cross hybrids can be beneficial alternatives for commercial single-cross hybrids and good elite sources for diverse inbred lines. A set of 22 genotypes comprised 10 population crosses, 10 top crosses, and two check cultivars were evaluated at Cereal Crop Research Institute, Pirsabak-Nowshera, in a randomized complete block design with three replicates in 2014. This research's major aims were to determine the magnitude of heterosis and the degree of character association between yield and its attributes to select superior genotypes from the breeding material. Data were recorded on maturity, and yield associated traits, where significant genetic variability was observed among the genotypes for all the studied traits except days to silking. Mean values for the studied traits ranged from 44 to 52 days for tasseling, 48 to 54 days for anthesis, 49 to 54 days for silking, -1.33 to 2.33 for the anthesis-silking interval, 2.53 to 8.47 kg for fresh ear weight, 12 to 16 rows for kernel rows cob-1, 27.15 to 37.49 g for 100-kernel weight and 2830 to 7649 kg ha-1 for grain yield. Days to silking, anthesis silking interval, and kernel rows cob-1 showed low broad sense heritability (12.08%, 24.84%, 27.59%), days to tasseling, days to anthesis revealed moderate heritability (40.53%, 36.62%), while fresh ear, 100-kernel weight, and grain yield exhibited high broad-sense heritability (94.89%, 82.33%, 90%). Negative and significant heterotic values were observed for maturity traits, while heterotic values were positive and significant for yield-associated traits. Correlation analysis revealed that characters like fresh ear weight (r = 0.93) and 100-kernel weight (r = 0.50) manifested a strong positive and significant association with grain yield. Based on mean performance and grain yield, promising hybrids were 3008F3 x 2007-WC and 3008F3 x 2010.
A Review on Pharmaceutical Waste Pollution in Water: Extent, Management and Removal Strategies
Pharmaceutical waste and presence of hazardous pollutants in them is a growing concern due to their fate, origin, higher rate of utilization and varying nature of active ingredients resulting in water contamination. However, there is few research on the graving nature of the problem. Cascading impacts on human and ecosystems can be expected from contaminated groundwater and other aquatic channels. While, various technologies used and studied for the removal/reduction/sedimentation of pharmaceutical pollutants. At the initial stages, level of toxicity should check with respect to flora, fauna, environment, and human health. Furthermore, the production of by-products from pharmaceutical pollutants should also be checked and regulated. These by-products can be much more toxic, than the original contaminants and can exert significant toxic effects. It was concluded that there should be ongoing efforts to reduce the cost associated with pharmaceutical waste and their pollutants removal processes to ensure sustainability in the environment and human being
Cell Transplantation Therapies to Reverse Type 1 Diabetes: A review
Stem cell technology is demonstrating promising advancements in cure of diseases due its differentiation ability. Type 1 diabetes is mainly caused by autoimmune β cells destruction. In this review, we focus on treatment procedures of Type 1 Diabetes (T1D) with numerous stem cells (SCs) i.e hPSCs, MSCs, hESCs, BMSCs, AFSCs, HSCs and islet cells (that are not stem cells but they are approved worldwide and are being successfully used to permanently reverse T1D). A brief overview of this disease along with the advancements in treatment of T1D with stem cells is discussed. Biomaterial encapsulation to avoid immune rejection and improved immunomodulation and immune tolerance via drugs /bioengineering techniques makes the outcomes of SC therapies more efficient and productive, hence, proving to be another future milestone of completely reversing type 1 diabetes especially in those patients who got clinically diagnosed at an early stage and then received prompt treatment of either restoration of already available β cells functionality or transplantation of purified and functional SCs differentiated insulin producing cells to normalize the glycemic control and homeostasis
Assessment of fish oil to check the stability and meat quality of some commercially available tin packed fish in Islamabad, Pakistan
Fish contains all the essential nutrients which is important for human health so it is important to analyse all the nutrients present in tin packed fish meat. Keeping in view its importance present study is conducted on the assessment of fish oil to check the stability and quality of fish meat by proximate analysis of commercially available tin packed fish. Four tin packed fish species i.e., Sardine (Sardinella longiceps), Red salmon (Oncorhynchus nerka), Pink salmon (Oncorhynchus gorbuscha) and Skipjack tuna (Katsuwonus pelamis) were collected from different supermarkets of Islamabad, Pakistan. Proximate analysis viz., crude protein, crude fat, moisture and ash contents of the fish meat has been done to evaluate the meat quality. The antioxidant activity in oil was also analysed by FRAP assay. The result indicated that maximum percentage of moisture i.e., 78.61% present in Skipjack Tuna meat, Pink Salmon contain highest percentage of crude protein i.e., 70.00%, Red Salmon contain highest percentage of crude fat i.e., 30.00% while Sardine and Skipjack Tuna contains highest percentage of ash contents i.e., 8.00% and the total antioxidant capacity (uM) is higher in oil of Red Salmon (24.35%) followed by Sardines (14.78%), Skipjack Tuna (9.86%) and Pink Salmon (9.48%). It was concluded that the fish meat after thermal processing contains suitable percentage of crude protein, crude fats, and moisture and ash contents
Invitro antimicrobial efficiency of Lawsonia inermis L (Henna) extracts against Multidrug Resistant Microorganisms
Abstract
Antibiotics are becoming less effective as drug resistance spreads throughout the world, making it ever more difficult to treat the disease. The effect of biotic stress on antimicrobial activity of Lawsonia inermis L. (Henna) was studied as an alternate to antimicrobial agents against multidrug resistant microorganisms. The study was carried out in Molecular Biochemistry Lab, Department of Biochemistry, University of Agriculture Faisalabad. The plant seedlings were given biotic stress with Fusarium solani. The induced extracts were harvested at different time intervals and the antimicrobial activity was investigated by disc diffusion method. The induced plant extracts revealed highest susceptibility against S. aureus (30±0.02) and Pasteurella multocida (30±0.01) at 12 hpi. The least activity was shown against all the strains at 0 hpi. The highest antifungal activity was found against Ganoderma lucidum (55±0.05) at 24 hpi. The results demonstrated a significant difference in the antimicrobial activities of all the strains with and without fungal stress (P<0.05). The fungal induced extracts of Lawsonia inermis L (Henna) with enhanced antimicrobial activity may have the potential of being alternative and cost- effective agents against antimicrobial resistance
Morphometric analysis of soldier cast of Odontotermes obesus (Rambur) and Microtermes obesi (Holmgren) (Blattodea: Termitidae; Macrotermitinae) from three localities of Potohar region, Pakistan
A great diversity of termite species is found all over the world, among these 53 species are identified from Pakistan. The knowledge about morphological features in soldier cast of termites is proved to be a technical tool for taxonomy and identification. In the present studies, the morphometric variations of external morphology in soldier caste of Odontotermes obesus (Rambur) and Microtermes obesi (Holmgren) from three different areas i.e. Gujar Khan (A), Rawalpindi (B) and Islamabad (C) were studied. About 36 characters like body, thorax, abdomen, from head to mandible tip, head, pronotum, postmentum, mandible, antenna (scape, pedicle, flagellum), and legs parts were used for morphometric measurements. The data were statistically analyzed for significant differences in their mean, standard deviation, standard error, 95% confidence interval, coefficient of variability and analysis of variance. “Student t-test” was used for the comparison of mean values using Minitab version 16. The results of the present study revealed no significant differences among the population samples collected from various localities. However little variations were observed in a few characters like antennal segments (pedicle, scape) and legs (trochanter, tibia) among the soldier cast which are adaptive in nature to survive in the environment
